To all whom it may concern: i

I Be it known that I, RUDOLF RADINsE, a cltizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new l and useful Improvements in Rotary Brushes, l of which the following is a specification.

This invention relates to rotary brushes, and especially to .that class of brushes in which the bristles -or wires or ,other abrasive devices are held by a plate or collar ada ted to fit on or be fastened to a rotary sha t. 4

The particular object of the inventiortis to provide improved means for holding the wires or bristles inplace, this result being effected b the useof a single plate with periphera tongues struck up at the 'edge thereof, these tongues serving to clamp or hold a Wire around which the bristles or their equivalents are bent.

The invention has the advantage that only a single central plate is necessary to hold the other parts of the brush in place, and accordingly the parts may be very cheapl constructed and assembled.

In t e accompanying drawings-Figure l is a 1an of the brush. Fig. 2 is a section on the ine 2 2 of Fig; 1. I

Referring specificallyl to the drawings, (i indicates a central plate having an axial hole 7 by means of which it may be fitted on a spindle orshaft and suitably attached by any appropriate means. At its outer edge this plate,.which is circular in plan, is provided with a series oftongues 8 which are integral therewith, the .plate and tongues being stamped from a single' piece of sheet metal. Thetongues are `alternately bent in opposite directions, so as to clamp a retaining ring 9 made of twisted wire or the like, into the bands or twists ofwhich ring thc wires, fibers or bristles 10 are 'woven or inserted, and then folded over so that the ends of the wires or bristles extend outends to the Work which may be applied to the brush. The tongues are preferably flared slightly at their outer ends, as indicated at 11, to avoid a shar edge which fracture the outwardly therefrom.

.ing a series of periphera tongues tions, or toward opposite sides of the plate, and the wire ring 9 with the bristles attached thereto is inserted between said tongues, which arevthen pressed together or clamped upon the wires, the tongues bein bent lover the ring 9 to clamp the same and thus hold the abrading wires or.l bristlesin position. Obviously cloth strips or other materials for forming a brush face may be used instead of wires or bristles, the strips or strands being'looped around the Wire ring 9 as shown, before the same is clamped by the tonguesof the plate. The single plate 6 with its tongues serves to hold the material of the brush in an effective manner, without the necessity for other clamping plates or devices, and it is Vobvious that the parts may all be cheaply constructed and easily as-4 sembled. To linsert new brush material it is simply necessary to pry thel tongues apart,. v permitting the removal of the wire 9 and the strands held thereby, and the substitution of new parts for those removed. If desired, a

wide brush may be built up of a number of retaining ring clamped by said tongues, and l fibers connected to said ring, and proJectmg 9. A rotary brush com rising al plate havtherefrom, a ring, andiibers `fol ed around saidv ring, the ring being clamped by the tongues and extending around the outer edge of the plate.

In testimony whereof, Ido afiix my signature in presence of two witnesses.
